Sorry dcdoug someone hasn't actually said what's going on, here's my take on it.
The secrecy surrounding the original cars is well deserved! If everyone knew all the little details of what it takes to confirm a "lost" or "recovered", "missing" original Cobra it makes it easier for an imposter to pass itself off as a real one. It HAS happened. A fake can be done SO well it has a chance of fooling even the most expert among those who "guard the secrets" of confirmation. Rumor has it, that actually happened for a time, with at least one car.
Jay Leno noted that due to the value of Dusenbergs there are now more "really official and verified" Dussey's out there than were originally manufactured! Some, like original Cobras, may actually be two cars! One with the "real" body, another with that bodies "real" chassis, for example. Or a wrecked Cobra, rebuilt, a "real" one, but somebody else holds the title! There's a bunch of ways to fake a car and with the high value on some, it's worth a significant investment to do so.
In spite of the secrecy I do enjoy the banter back and forth, the rumors, the mystery of a new "find", it's kind of like a game that's interesting even if I don't know all the rules.
In this case I'm not sure what Mr.Bruce has up his sleeve, but I'm watching him like a hawk... Da bunnies know...
